(RNN) – With the federal government shut down because Congress cannot agree on a spending bill, some are surprised about what services, museums and other agencies are open for business and which aren't. By the way – Congress is still getting paid.

Here is a list of what's closed, open, or operating with essential employees.

Aviation – The Federal Aviation Administration is partially shut down, meaning the air traffic controllers are on the job. More than three-quarters of inspectors are still on furlough after about 600 were recalled a week into the shutdown.

Defense - Military service members continue to work. Only Department of Defense civilians performing essential activities continue to work. The Department of Homeland Security is partly shut down. Some U.S. Citizenship and Immigration services will continue to operate. Applications, forms, wait times, and more remain either limited or available online, except for E-Verify.

Active military will remain on the job without interruption to their pay after a bill the president signed into law Oct. 7. The U.S. Coast Guard continues to operate, including military functions, port security, search and rescue, and maritime safety. Half of civilian military workers will be furloughed. The Nuclear Facilities Safety Board operates at full functionality.

Head Start issued a statement saying 19,000 children in 11 states are now without grant funding due the shutdown; many have already closed or are in danger of closing soon. Programs in Massachusetts and Florida are operating for the time being using local and state funding.

Energy - The Department of Energy will operate with limited personnel, meaning research projects will shut down. The Defense Nuclear Facilities Safety Board is open – but if the shutdown lasts for a while, 100 employees will be furloughed. The Federal Energy Regulatory Commission will shut down except for inspections and electric grid monitoring.

Employment - Staffers in the worker compensation and mine safety divisions will remain almost completely staffed. Workers in the Occupational Safety and Health Administration (OSHA) and Bureau of Labor Statistics would be mostly furloughed.

Environment – The Environmental Protection Agency is mostly closed, but will respond to emergencies.

Federal courts – The federal court system can operate for 10 days using reserve funds.

Financial - The Internal Revenue Service will discontinue a host operations - including audits, examination of returns and manual collections. The Federal Reserve remains open with normal staffing. The Financial Management Service (FMS) and General Services Administration (GSA) are in partial shutdown. The Federal Trade Commission is also shut down for services other than those that would prevent a threat to human life or property.

Health - The Centers for Disease Control and Prevention (CDC) is telling more than two-thirds of its workers to stay at home, meaning potential outbreaks will not be investigated. Flu vaccines will be delivered to doctor's offices, but the agency will not track flu cases.

The National Institutes of Health (NIH) is not taking new patients or initiating new clinical trials at its clinical center. However, trials that were in process before the government shutdown continue.

Health Insurance Marketplace – Consumers can go to HealthCare.gov to find the state marketplace to serve them and can apply and choose a plan, with coverage beginning as early as Jan. 1, 2014.

Home loans – The Federal Housing Administration is not making new home loan guarantees during the shutdown.

Jobs – Government jobs will be available and updated on USAJobs.gov. Job applications may not be processed at advertising agencies until the government reopens.

Medicare and Medicaid – Medicare and Medicaid benefits continue, though benefits could be affected in the event of an extended shutdown.

NASA - The agency is not allowing tours of its facilities, and it has shut down its TV channel and website. However, mission control support and other essential activities will continue.

Nutrition - The U.S. Department of Agriculture will continue meat and poultry safety inspections, but its website has been shut down. The Supplemental Nutrition Assistance Program, the food stamps program known as SNAP, will continue for a month.

However, Women, Infants and Children (WIC) is open in some states and not others. WIC helps pregnant mothers and their families and affects 9 million people. Douglas Greenway, president of the National WIC Association, told the Huffington Post the USDA is helping the neediest states with contingency funds. But once those funds run out, likely by the end of October, those programs also will shut down.

The USDA will continue to monitor meat and poultry safety, however, the agency warned a prolonged shutdown "would affect the safety of human life and have serious adverse effects on the industry." Conversely, daily inspections and lab testing for food contamination by the Food and Drug Administration is on hold because nearly half of its workers are on furlough. Workers will respond to emergency cases only.

Operating Status – Visit the U.S. Office of Personnel Management for the most up-to-date operating status of the federal government.

Patents and trademarks – The U.S. Patent and Trademark Office remains operational for the next few weeks using reserve funds.

Recreation - The Department of the Interior is partially closed, but it affects more than you think. The number of agencies that fall under it are myriad. Want to go to a national park or museum, such as the Smithsonian or even a presidential library? Sorry, national parks and landmarks are closed to the public. You can't even stay at home and watch the National Zoo "Panda Cam."

However, the White House announced Oct. 10 parks could reopen if states where they are located funded their operation.

Other agencies that fall under this umbrella agency include: National Park and Wildlife Refuge Systems, Bureau of Land Management, U.S. Geological Survey (only responding to emergencies), the Bureau of Ocean Energy Management and the Bureau of Indiana Affairs (partially closed, meaning people will get their benefits, but that's it).

Small business loans – The Small Business Administration is not processing applications of business loans during the shutdown.

Social Security – Some services will be unavailable, but Social Security payments will continue to go out.

Travel – The Transportation Security Administration continues passenger, baggage screening and operation of the Federal Air Marshal Service. Rail networks and traffic control operations will also continue. Expedited passports that were already in progress will be processed, but no new passport applications will be accepted during the shutdown. The State Department will continue to issue travel warnings and emergency services for U.S. Citizens abroad.

Veterans' Services – Medical services will continue to be provided by the Department of Veterans Affairs, but benefit programs may be affected.

Weather – The National Weather Service continues to issue weather alerts, forecasts, and warnings. The same goes for the National Oceanic and Atmospheric Administration, although research operations will cease.

Miscellaneous:

Delta Regional Authority - Provides services to 252 counties and parishes across eight states that border the Mississippi River, will remain open using reserve funds.

The Denali Commission - Provides physical and economic support for areas in Alaska and will continue operation.
